I'm failing smog. Eng. has 50 miles on a rebuild. I have a brand new cat. A mechanic and several friends think it is because my cheapo FOCUZ header has the O2 sensor up on one of the tubes before they all meet. So the O2 sensor is only reading one cylinder.

Does anyone have a stock exhaust manifold i could buy or borrow for a day or two? I'm in the Seattle area. I need it as absolutely soon as possible.

Thanks

 

Oh I forgot to say it's for a 1991 EF Si hatch w/ a stock D16

 

B or D series?

EDIT: I have a b-series

 

D series

 

I have a couple up here in bellingham if it gets that desperate.

I'm sure a junkyard would be willing to part with the exhaust manifold for not too much money.

 

wait, did you fail before or after the new cat (or both)?

if before, or both, how much did you pay for the new cat?

 

i failed before i put the cat on. then again after. i bought the cat a while ago though. i'm gonna try a new O2 sensor first.

Do you think the price of the cat can be used towards the waver ****? even if i bought it a while ago?

I have a fuel reg. so i'm gonna lean the **** out of it and put a new O2 sensor on and try again. the more I talk to people it seems the manifold itself shouldn't make that much of a difference.

If anyone else has imput it is much appreciated.
